BENJAMIN A. PARKER, OF NEW HAVEN, CONNECTICUT, ASSIGNOR TO THE E. B. IVES 00., OF NEW HAVEN, CONNECTICUT.

CASEMEN'I Application filed November This invention relates to improvement in asement operators, such as are commonly employed in operating French windows or shutters, the object being to produce operating and locking mechanism which will be simple in operation and positive in action, and the invention consists in the construction as hereinafter described and particularlarly recited in the claims.

Fig. l is a plan view of a casement operator constructed in accordance with my in vention and shown in the open position by broken lines.

Fig. 2 is a broken plan view, partly in section, on an enlarged scale, of the opera tive parts of the device.

Fig. 3 is a sectional view on the line 33 of Fig. 1.

Fig. 41- is a sectional view illustrating a modified "form of my invention.

In carrying out my invention, I employ a round post 5 extending upward from a base 6, which is adapted to be secured to a window sill. Setting over this post is a yoke 7, formed with a head 8 in which an operating-rod 9 is mounted, this rod extending through an eye or loop 10 secured to a case ment-closure 11. The yoke is formed with inwardly-entending lugs 12 and 13, between which is mounted a handle let, this handle being connected by a pin 15, or other means, with a screw 16 which extends through one lug and into engagement with the other lug. Preferably, the center of the post will be removed to save metal, and the yoke will be held in place upon the post by a cap-plate 17 secured by screws 18.

When the handle is raised to a horizontal position, as shown in Fig. 2, the screw will be turned to force the lugs apart, and hence permit the yoke to freely turn upon the post 5, and as the yoke is turned by the handle, the easement will be moved to an open posi tion, as shown in broken lines in Fig. 1. When the easement is moved to the desired position, the handle 14 will be depressed, as shown in broken lines in Fig. 3, and in depressing the handle, the screw 16 is turned so as to draw the lugs 12 and 13 together and so clamp the yoke firmly to the post. Thus, by simply moving the handle, the easement can be unlocked, turned, and r locked.

27, 1925. Serial No. 71,547.

It will be understood that the parts are arranged for rightand left-hand casements.

It is obvious that, instead of forming the screw separately from the handle, the head 19 of the handle might be formed on opposite sides with integral, reversely-threaded screws 20 and 21, respectively engaging with nuts 22 and 28 which enter seats 2% and in the outer faces of the lugs 12 and 13, as shown in F ig. i of the drawings, the operation of the device being the same as above described, as the movement of the handle will turn the head 19 in one direction or the other, so as to separate the lugs or draw them toward each other, to cause the yoke to clamp the post.

I claim:

1. A casement operator, comprising a round post, with means for mounting the same, yoke set over said post and formed with a head and with two inwardlyprojecting lugs, a rod mounted in the head and having sliding engagement with a casement closure, and a handle mounted between and connected with the lugs, whereby turning the handle in one direction will expand the yoke and in the opposite direction will contract the yoke.

2. A casement operator, con'iprising a round post, with means for mounfng the same, a yoke set over said post and formed with. a head and with inwardly-projecting lugs, a rod mounted in said head and having sliding engagen'ient with the casement-clos ure, a screw extending through one lug into engagement with the other lug, and a handle connected with said screw.

3. A easement operator, comprising a round post, with means for mounting the same, a yoke set over said post and formed with a head and with inwardlyprojecting lugs, a rod mounted in said head and having sliding engagement with the casementclosure, a screw extending through one lug into engagement with the other lug, a handle connected with said screw, and a cap set over the edge of the yoke and secured to the said post.

In testimony whereof, I have signed this specification.

BENJAMIN A. PARKER.
